Dolphin Facts and Information Dolphin Facts and Information Presentation Transcript

  • Facts about Dolphins www.dolphins-world.com
  • Dolphins are Mammals As all mammals, dolphins nurse their kids from mammary glands.
  • Dolphins can swim up to 260 m. below the surface of the ocean. However dolphins are mainly shallow divers as they need to reach continuosly the surface to breathe.
  • Dolphins can stay up to 15 minutes under water They only do this rarely as they usually stay only a few minutes diving before reaching the surface for air.
  • Dolphins use a technique called echolocation This technique uses the same principles of a radar, and it is used to find food and navigate
  • Dolphins are social beings Dolphins live in groups and cooperate among each other for activities like getting food and calf rising
  • Dolphins are Cetacenas Dolphins are closely related to Whales and Porpoises. There are 37 species of ocean dolphins which belong to the family Delphinidae and 5 species of river dolphins.
  • Dolphins are warm-blooded As mammals, dolphins are warm blooded and their internal temperature is around 36 degrees. To conserve this temperature they are surrounded by a thick layer of fat called “blubber” just below the skin.
  • The largest dolphin is the Orca, also known as “killer whale” Orcas grow up to 6.1 meters long and they are named as “whales” because their size, but they really belong to the toothed cetacean family just like dolphins do.
  • The most popular dolphin is the “bottlenose dolphin" Bottlenose dolphins (Tursiops Truncatus) are the ones we have seen in tv series, movies and aquatic shows. Bottlenose dolphins can grow up to 2.5-2.8 meters.
  • Dolphins communicate efficiently Dolphins can make a unique signature whistle that may help individual dolphins recognize each other, collaborate and perform several other kinds of communication.
  • Dolphins can swim 5 to 12 kilometers per hour This will depend on the species and situation, although fastest dolphins can reach up to 32 km/h.
  • The botllenose dolphin brain weighs 1500-1600 grams The average human brain weighs 1200-1300 grs. While this is not a conclusive evidence of dolphin intelligence as many other factors might be the cause of intelligence according to scientists, it is one of the ways to measure intelligence.
